and the output of the control module is connected with the control end of the resonance control switch Q5, and the control module controls the on-off of the resonance control switch Q5 so as to adjust the resonance parameters of the resonance loop formed by the first induction coil L1.
The charging module is used for reducing the voltage of the input mains supply, the first induction coil L1 in the aerosol generation module is combined with the second induction coil L2 in the charging module for electromagnetic induction charging, so that the working voltage after reduction is transmitted from the second induction coil L2 in the charging module to the first induction coil L1 in the aerosol generation module in an electromagnetic induction manner, the current in the aerosol generation module is increased, the resonance control switch Q5 is controlled by the control module to be turned off, the current can flow to the battery for charging, conversely, when the battery is fully charged, the control module obtains a signal that the battery is fully charged and controls the resonance control switch Q5 to be turned on, so that the adjusting capacitor C3 is connected with the first induction coil L1 in parallel, the resonance frequency of a resonance loop formed by the first induction coil L1 is reduced, the loop presents capacitive impedance, and the charging current in the loop is reduced, so that the resonant current flowing through the second induction coil in the charging module is simultaneously reduced.
In this embodiment, the control module can specifically include the control module of module and the control module of the module that charges that the aerosol takes place the control module control aerosol of module and takes place the components and parts in the module, and the control module control of the module that charges components and parts in the module.
The first induction coil L1 of the aerosol generating module may have a vertical spiral shape, wherein the first induction coil L1 may spiral up around the aerosol generating module. The first induction coil L1 may also be a planar spiral. The first induction coil L1 and the second induction coil L2 are mutually inducted, so that the electric energy in the charging module is converted into magnetic energy and transmitted to the first induction coil L1 of the aerosol generation module, and the magnetic energy is converted into electric energy by the first induction coil L1 of the aerosol generation module and stored in the battery to finish charging. The magnetic shielding sheet can be added to the periphery of the second induction coil L2 to gather magnetic energy, so that the conversion efficiency of the energy from the second induction coil L2 to the first induction coil L1 of the aerosol generation module is improved. In this embodiment, the first induction coil L1 of the aerosol generating module has 9-10 turns, a wire diameter of 1.2mm, about 200 strands of single-strand external insulated copper wire, an inductance of about 10 microhenries to about 10 henries, and a winding diameter of about 15 mm. The number of turns of the second induction coil L2 of the charging module is larger than that of the first induction coil L1, wherein the number of turns of the second induction coil L2 of the charging module is mainly 13-14 turns, the wire diameter is 1.2mm, single-strand external insulated copper wires are contained, about 200 strands are contained, the inductance is about 10 microhenries to 10 henries, and the winding diameter is about 25 mm.
In this embodiment, the aerosol generating module may further include a first field effect transistor Q1 and a second field effect transistor Q2, wherein a source of the first field effect transistor Q1 is connected to a drain of the second field effect transistor Q2 and to the first capacitor C1; the source of the second field effect transistor Q2 is grounded and is connected with the first induction coil L1; the drain electrode of the first field effect transistor Q1 is connected with a battery, and the grid electrode of the first field effect transistor Q1 and the grid electrode of the second field effect transistor Q2 are respectively connected with the control module of the aerosol generation module; the control module of the aerosol generation module is respectively connected with the grid of the first field effect transistor Q1, the grid of the second field effect transistor Q2 and the base of the resonance control switch Q5, and then the control module of the aerosol generation module controls the first field effect transistor Q1, the second field effect transistor Q2 and the resonance control switch Q5 to be switched off, wherein the resonance parameters of the resonance circuit formed by the first induction coil are adjusted by controlling the on-off of the resonance control switch Q5.
The aerosol generating module may have a heating mode of operation and a wireless charging mode for heating the aerosol substrate and wireless charging, respectively. The first field effect transistor Q1, the second field effect transistor Q2, the first induction coil L1 and the first capacitor C1 form a half-bridge resonant electromagnetic heating circuit. The battery is powered in the wireless charging mode, and the first field effect transistor Q1 and the second field effect transistor Q2 are controlled to be switched on and off through the control module of the aerosol generation module, so that the heating of the aerosol substrate can be realized. On the basis of a half-bridge resonant electromagnetic heating circuit, the adjustment capacitor C3 and the resonant control switch Q5 are added, the control module of the aerosol generation module is matched with the control module to cut off and conduct the first field effect transistor Q1 and the second field effect transistor Q2, and wireless charging of a battery can be achieved. The wireless charging circuit is constructed by multiplexing the first induction coil L1 and the half-bridge resonant electromagnetic heating circuit, so that the use number of components can be reduced, the cost is reduced, and the size is reduced; the arrangement of charging interfaces can be reduced, and the aerosol generating device is convenient to design in a waterproof and dustproof mode.
For example, the resonant frequency of the resonant circuit formed by the first inductive coil L1 and the first capacitor C1 may be 200 Khz. When the aerosol generating module is in the heating operation mode, the control module of the aerosol generating module can provide complementary PWM pulse control signals with 200Khz frequency to the gates of the first field effect transistor Q1 and the second field effect transistor Q2, so that the first field effect transistor Q1 and the second field effect transistor Q2 are complementarily turned on with 200Khz frequency, and high-frequency current which changes at high speed flows through the first induction coil L1, so as to generate an alternating magnetic field which changes at high speed. The heating body is arranged in the alternating magnetic field, can induce and generate vortex to generate heat, and then heats the aerosol substrate to generate aerosol. It is understood that the resonant frequency of the resonant circuit formed by the first inductive coil L1 and the first capacitor C1 may have other values.
The heating element can be made of any material capable of generating induced current in the alternating magnetic field, and is most commonly metal, such as iron. It is understood that the heating element may be a component of the aerosol generating device, and may be disposed at the center of the first induction coil L1. The heating element may be built in the aerosol substrate, not belonging to the aerosol generating device; when the aerosol substrate is inserted into the aerosol-generating device, the heat-generating body is located at the center of the first induction coil L1.
When the aerosol generating device is plugged into a charging seat and is in a wireless charging mode, the alternating current voltage of the second induction coil L2 is induced to the first induction coil L1, and the induced current is rectified by the first field effect transistor Q1 and the second field effect transistor Q2 and then output to the battery VBAT, so that wireless charging is completed. The resonant current of the second induction coil L2 can be configured to be low (for example, the resonant current in the wireless charging mode can be 500mA, and the current flowing through the first induction coil when the heating element is normally heated and operated is generally 1A-4A), and the induced eddy current energy is not enough to allow the heating element to generate too much heat.
In this embodiment, in order to reduce the temperature of the heating element heated by magnetic induction during wireless charging and reduce the problem of electric energy waste caused thereby, a magnetism isolating ring may be disposed at the center of the charging seat, and when the aerosol generating device is inserted into the charging seat, the heating element is inserted into the magnetism isolating ring, so that the heating element is not affected by the magnetic field of wireless charging.
In other embodiments, in order to reduce the power loss caused by the induction heating of the heating element during the wireless charging, the operating frequency of the first induction coil L1 during the heating operating mode of the aerosol generating device may not be equal to the operating frequency of the first induction coil L1 during the wireless charging, or even the difference between the two may be relatively large.
Of course, in another embodiment, the first induction coil L1, the second field effect transistor Q2 and the first capacitor C1 are connected in parallel to each other and to the source of the first field effect transistor Q1, wherein the first induction coil L1 and the first capacitor C1 form a parallel resonant circuit.
And (3) charging process: the induced current (i.e., charging current) on the first induction coil L1 may have a positive half-cycle and a negative half-cycle. When the induced current is a positive half cycle (for example, the current direction on the first induction coil L1 is upward), the control module of the aerosol generating module controls the first field effect transistor Q1 to be turned on and the second field effect transistor Q2 to be turned off, and the induced current flows through the first capacitor C1 and the first field effect transistor Q1 to charge the battery. When the induced current is a negative half cycle (taking the direction of the current on the first inductor L1 as an example of a downward direction), the first fet Q1 is controlled to be turned off and the second fet Q2 is turned on, and the induced current flows through the second fet Q2 and forms a loop with the first capacitor C1.
In this embodiment, the aerosol generating module further includes a first resistor R1, and the first resistor R1 is connected to the control terminal of the resonance control switch Q5.

During heating, or during wireless charging and when the battery is not fully charged,the resonant control switch Q5 is off. When the control module in the aerosol generating device detects that the battery is full, the resonance control switch Q5 is intermittently switched on and off according to a self-determined protocol to change the resonance parameters of a resonance loop formed by the first induction coil L1: when the resonance control switch Q5 is turned on, the adjusting capacitor C3 is connected in parallel to two ends of the first induction coil L1; from formulas
It can be seen that when the capacitance C becomes larger, the resonant frequency F becomes smaller and deviates from the original operating frequency, the circuit presents a capacitive impedance, so that the charging current in the circuit becomes smaller, and the resonant current of the resonant circuit in the charging module decreases at the same time.
